针对中压配电网新能源并网节点柔性互联,提出一种集成光储中压并网的智能软开关(SOP),兼具高效汇集光储资源和改善配电网潮流不均衡分布能力。首先,介绍了光储混合级联SOP(PVBH-SOP)拓扑结构,给出了单级式隔离级联子模块拓扑及其调制策略。其次,建立了PVBH-SOP平均电路模型,分析了其潮流调控原理。然后,给出了PVBH-SOP的3种运行模式,设计了相应控制策略。最后,在MATLAB/Simulink仿真平台上搭建了一套10 kV/2 MW的PVBH-SOP系统,验证了所提PVBH-SOP拓扑与控制策略的有效性。
Aiming at the flexible interconnection among renewable energy grid-connected nodes in medium-voltage distribution networks
a soft open point (SOP) integrated with photovoltaic and energy storage for medium-voltage grid connection is proposed. This SOP has the capability to efficiently aggregate photovoltaic and energy storage resources and to improve the uneven distribution of power flow in distribution networks. Firstly
the topological structure of the photovoltaic-battery-hybrid cascaded SOP (PVBH-SOP) is proposed and the topology and modulation strategy of its single-stage isolated cascaded sub-modules are presented. Secondly
an average circuit model of the PVBH-SOP is established to analyze the control principle of its power flow. Then
three operation modes of the PVBH-SOP are described
along with their corresponding control strategies. Finally
a 10 kV/2 MW simulation platform for the PVBH-SOP system is established in MATLAB/Simulink to verify the effectiveness of the proposed PVBH-SOP topology and control strategy.
